= 60 F Glycerine (sg = 1.24) flows in a copper tube. However, this chemical process requires that the Reynold's Number never be larger than 300. What is the smallest standard Type K copper tube that will carry a flow of 0.9 ft/s? Given that flow rate and tube, what is the pressure drop between two horizontal points 55 ft apart (positive number)? Dmin (ft) Tube NR f h (ft) Ap (psi)
